Abstract

The purpose of this research are: (1) to design the development of mincester media to increase the learning achievement of the system controlling electromagnetic; (2) to describe the effectiveness the use of mincester media to increase the learning achievement of the system controlling electromagnetic. The subjects of these research are the students at Politeknik Raflesia electrical engineering major. While the object this research is mincester media as a treaning media the system controlling electromagnetic. This research was conducted using the approach of Research and Developmen (Research and Development). Based on the analysis that was conducted in this research, so it can be taken conclusion that: (1) minceste rmedia as a learning media that can exlain working principles of the system controlling electromagnetic components which abstract become concrete and attract the students’ attention so that it can increase the achievement in students’ learning. (2) mincester media is developed. It’s alternative media that is very effective as a learning media of the system controlling electromagnetic to increase the learning for students at Politeknik Raflesia electrical engineering major. The improvement of this achievement is very significant by t-test results 0.00 significance level of less than 5%. The use of mincester media can increase learning motivation. The learning motivation of the students' after using this mincester media is higher than before using minceste rmedia.

Abstract

Hampir 70 % energi yang dihasilkan pembangkit dikonsumsi oleh motor- motor listrik. Penggunaan motor induksi pada industri maupun pabrik-pabrik lebih menguntungkan dibandingkan motor DC maupun sinkron, salah satu keuntungannya adalah perawatan mudah dan efisiensi tinggi Pada mesin-mesin di industri pengaturan kecepatan mutlak dibutuhkan. Seiring dengan perkembangan elektronika daya, hal ini menjadi sangat mudah untuk dilakukan, yaitu dengan menyuplai motor dengan inverter variable speed drive (VSD). Dengan suplai Variable Speed Drive, pengaturan kecepatan motor sangat mungkin untuk dilakukan yaitu dengan mengatur frekuensi tegangan. Penelitian ini dilakukan untuk mengetahui pengaruh penggunaan inverter Variable Speed Drive terhadap kinerja motor induksi tiga fasa. pengujian dilakukan pada frekuensi 50 Hz (frekuensi jala-jala), 30, 35, 40, 45, 50 Hz (frekuensi inverter) dan motor dibebani sebesar 0.5, 1, 1.5, 2, 2.5, 3 Nm. Dari penelitian yang dilakukan diperoleh kesimpulan antara lain, penggunaan inverter Variable Speed Drive mengakibatkan efisiensi motor menjadi lebih baik saat disuplai dari VSD
